One of the things that always gladens my heart at this time of year is when the song thrushes begin singing again. They always seem to start early on in the year.
However, one of the things I have noticed, and I am wondering if it is just me, is that song thrushes sing louder and higher in the trees at the start of the year. As the year progresses they become more subdued and come down into the undergrowth more.
I'm sure there are good behavioural reasons for this (I can think of several) but it's noticing things like this that make the experience more than just listening to a bird singing a pretty song.
